Description of the invention: [Technical field to which the invention belongs] '纟发明#' relates to a kind of motor control technology, especially a sensing method for distributing a wound brushless DC motor (4) and a method for the same Fixing frame. [Prior Art] Since the invention of the electric motor, it has been continuously updated, from the earliest DC motor and AC motor to the current brushless DC motor (BrushCh DC motor, BDCCh-like DC motor transmits DC power to the battery through the carbon brush The current transformer (c〇mrou1: at〇r), the current transformer then introduces the power source into the coil on the rotor to generate an electromagnetic force, and the electromagnetic force and the permanent magnet on the stator exert a push-pull action to generate a rotation. The direction of the electromagnetic force changes. It relies on the current transformer to change the contact carbon brush during the rotation process (the current transformer is installed on the rotor as the rotor rotates). Different carbon brushes have different polarities, which can change the current direction. The configuration in which the brush is in contact with the electric & flow converter creates a number of disadvantages, such as frictional 'consumption of unnecessary dynamic energy loss, increased contact resistance of the contact interface, resistance to power transfer, current exchange on the contact surface and spark interference The electronic cleaning of the carbon brush is a nightmare for the practitioners. As for the principle of the AC motor, Taking advantage of the polarity change of the alternating current itself, the alternating current is introduced into the stator coil that is not moving, and the direction of the magnetic field is changed, and the magnetic field interacts with the permanent magnet provided on the inner rotor to generate rotation. The alternating current motor completely eliminates the DC motor. The various shortcomings caused by the contact between the carbon brush and the current converter are the most widely used electric motors of 110892 5 200952602. The efficiency of the electric motor is large, but the speed control of the AC motor is difficult. To change the speed, the frequency of the alternating current must be controlled. It will change its torsion force, and at the same time it is useless for applications where only DC can be provided. For example, information products and electric vehicles are useless. According to the brushless DC motor, the advantages of the above two motors are taken, and there is no brush. The structure does not have many troubles caused by contact friction, and the use of direct current technology makes control more convenient. The principle and structure of the brushless DC motor are very similar to those of the alternating current motor. Basically, the rotor is made of a permanent magnet group. The magnetic properties are not changed, and the stator is exactly the same as the AC motor. The wound coil generates a magnetic force. ❹ Fig. 1 and Fig. 2 show a simple schematic diagram of the principle of operation of the brushless DC motor. As shown in Fig. 1, the rotor 10 is composed of permanent-cut iron of different polarities, and the stator 11 and the stator 12 It is a general coil electromagnet, which is produced by the revolving current. The N and s indicated on the figure represent the north and south poles of the magnetic field. The motor of the i-th diagram is in the initial state, and the current is from above the stator 11 and the stator 12. In other words, the arrow on the coil represents the direction of the current, and the generated magnetic field attracts the rotor magnets of different polarities, causing the two ends of the rotor 10 in the initial state to start to approach the stator U and rotate in a clockwise direction. Further, as shown in Fig. 2 It is shown that when the rotor 1G is approached by the first picture of the first picture, the current is turned on, and the direction of the magnetic field of the original electromagnet is changed, and the rotation is changed to push the end of the rotor away from the stator. u and the stator 12' continue to clockwise by changing the direction of the magnetic field by the direction of the current input 110892 6 200952602 * r. The moving side will continue to continue to achieve the rotor 10 Smooth rotation. On the shell, the motor has a more complex design and adds more stators to improve performance. In order to achieve an appropriate magnetic field direction according to the position of the rotor 10: a Hall sensor is introduced to determine the position of the rotor, the Hall sensor is a sensing element having a direction of detecting a magnetic field, and the principle thereof is wide. For the head of the class, it is not mentioned here, but only the structure and method for the erection of such a Hall sensor are discussed. ❹ < Fig. 3 shows the stator structure of a conventional brushless DC motor. The stator is wound around a coil, and the windings are wound around the individual solid positions of the stator 2 1 at individual fixed positions. The coils formed by stacking the windings 20 and the stacked coils at the fixed positions of the other stators do not overlap each other, so it is called a concentrated winding. The stator 21 is provided with an insulating frame 22 protruding from the winding 20 on the inner and outer rings for fixing the Hall sensor (described later). As shown in FIG. 4, the stator 21 and the Hall sensor circuit board 24 are combined in a conventional brushless DC motor by first pressing the stator 21 into a casing 25' and then applying a brushless DC motor. (BLDC) the rotor 23 is placed, and finally the Hall sensor circuit board 24 is placed on the top of the insulating frame. 0. However, the device technology of the Hall sensor is only suitable for the new mold opening. The scorpion,, and mouth structure, because today's brushless DC motor is still in the development stage, the market = off the spare parts, such as the use of concentrated winding method to make the brushless reach, although some can reduce the overall thickness and The advantages of magnetic field control are simple, but the industrial model mouth involved in the production of the motor is not just a single research.] 〇892 7 200952602 $ The manufacturer of the speed-producing motor has invested huge amounts of money to develop the system and the mold, in order to Achieving an effective production scale to reduce costs' All Weishang companies are daring to change existing production standards. - Therefore, the industry has the use of brushless DC motor and AC motor structure, the (four) nature of the AC motor stator installed in the brushless DC motor technology = known as knife-wound brushless DC motor, such as Figure 5 is a schematic view of a conventional AC motor stator, which uses a (four) coil winding method to distribute the coils: the type of winding 40 is overlapped in the stator 42 (for the sake of clarity, only the portion 〇H line) is displayed. The foregoing techniques for concentrated coil winding are completely different, and the advantages of distributed winding coils are widely known and will not be described herein. However, the maximum severance of the stator 42 in the application of the brushless DC motor is due to the convex height 41 generated by the distribution around the coil, which hinders the Hall sensing piracy space, and the stator 42 is also lacking in installation. The corresponding sensor of the sensor is only awkward. In view of the above, the lack of the prior art and the difficulties of the existing market ecology, how to fix the structure of the Hall sensor on the conventional AC motor stator without changing the existing motor production tools and standards The method and the method make the low-cost reliable traditional AC motor stator can be used as a developing brushless DC motor supply component, which has become an urgent problem to be solved in the technical field. SUMMARY OF THE INVENTION In view of the above-described deficiencies of the prior art, the present invention is directed to a sensor fixing method for a motor stator for fixing a sensor to a distributed wound brushless DC motor and to the method The sensor is fixed 110892 8 200952602 ... "The motor stator used as the small ~ π conventional Wei I type parent flow motor can be a motor stator of a cloth wound brushless DC motor. Another object of the present invention is to provide - a box, a cost-effective sensor fixing method and a fixture for the same. 4 gas for the purpose of lifting and others, the present invention provides a fixing frame for The sensor is fixed to a distributed winding motorless stator, and the motor stator has a __ & human motor 啕 ligature, the sensor ❹ fixed frame comprises: a frame; the second combination a portion formed on the bottom surface of the frame for coupling the first joint portion; the fixing portion is located at one end of the frame body away from the second joint portion for fixing the sensor. The aforementioned sensor holder Medium The first end of the joint portion forms an arc having a curvature having the same curvature as the center of the curvature and the periphery of the motor stator. The surface of the frame body is provided with an adjustment slot, and the second joint portion is adjacent to the frame body.
